I would like to get some feedback from users that might be rendering OSG terrain built with osgdem on Windows XP. Based on previous discussions, I understand that the terrain rendering on Windows does not have as good of performance as on Linux, however, I'm seeing abysmal frame rates when I'm rendering terrain on Windows. The paging performance is horrible. Perhaps it's the way I'm constructing my terrain or the setup in my OSG app.I'm not sure.
While I don't understand the algorithm that is being used for OSG terrain, I would expect it to perform as good or somewhat close to other Windows based earth viewers such as NASA's WorldWind which seems to run just fine on Windows with large databases. For the record, here's the osgdem command I'm using to build the terrain. osgdem -TERRAIN -PagedLOD -geocentric -t dted -d texture -l 10 -o terrain/wasatch_utm.ive Any input on the matter would be appreciated. -Shayne
